Operation Instructions (OIs) as well as Interpretations were created to supplement and clarify the provisions of the statute and regulations. These materials usually are not included in the regulations because they deal generally with procedural matters and do not deal directly with application and benefit requirements. They are still a useful tool to help you understand how the DHS Bureaus performs their different immigration services and enforcement functions. Users of the Operation Instructions and Interpretations should always consult the relevant regulations and manuals in conjunction with these materials. As the Bureaus have grown, the trend has been towards inclusion of more materials in the regulations and field manuals, and the Operations Instructions and Interpretations have been updated less frequently.
